multiple cursor with date handling issue reg

Dear all,
i am using three cursors in one pl/sql block each of this three cursor will fetch data based on column of date data type.i believe due to each condition relate to same table,contradiction may arise i.e

1> when code will execute , cursor c1 will do the job perfectly but c2 & c3 here may not be able to solve the purpose since the job has already been done by cursor c1 which i am not sure.my doubts i need all cursor to work based on each condition.
any suggestion from your side could sort out this issues.

As for your concern that the cursors 'may not be able to solve the purpose' I wonder why you think such things. I suggest you run the queries in sequence and note that they do, indeed, 'solve the purpose'.

Thanks sir for ur kind responce,yes i agree this will definitly work,what my intention was that all the three cursor are doing the same job based on different condition.if u can see c2 and c3 .

cursor c2---> lastmoddate< sysdate - 1

cursor c3 ---> lastmoddate< sysdate - 14

job of cursor c3 is already been done by c2 since sysdate - 14 < sysdate - 1,this may cause a replicate of data when c3 will start execute.what i need here is in order to avoid the replicate of data can i merge all the job into single cursor ??? will it work !!!
